A slit of width d is placed in the path of the beam of wavelength lambda . The angular width of the principle maximum obtained is:

A monochromatic light of wavelength 500 nm is incident normally on a single slit of width 0.2 nm of produce a diffraction pattern. Find the angular width of the central maximum obtained on the screen. Estimate the number of fringes obtained in Young's double slit experimental with fringe width 0.5 mm , which can be accommodated within the region of total angular spread of the central maximum due to single slit.

In single slit diffraction of light of wavelength lambda , angular width of the central maximum (considering slit width d) will be
